Please refer to Fig. 3, Fig. 3 is the schematic diagram of an electronic system 30. As shown in Figure 3, electronic system 30Comprise a master controller 300, a serial interfaces 302 and one or more peripheral device 304. Master controller300 can be a desktop personal calculator, and it roughly comprises a processor, a memory module, an inputInterface, an output interface and one soft/firmware interface etc. Master controller 300 is except providing user to carry outOutside nonidentity operation, also can provide user to integrate that multiple peripheral devices carry out transfer of data and data are standbyPart, further set up individual numerical data base. Specifically, master controller 300 passes through serial interfaces302 connect multiple peripheral devices 304, and wherein serial interfaces 302 can be an inter-integrated circuit(Inter-IntegratedCircuit，I2C) data/address bus, or a serial peripheral interface (SerialPeripheralInterface, SPI) data/address bus etc., in order to master controller 300 and peripheral device 304 to be providedBetween communication bridge, common if master controller 300 accesses are from data of peripheral device 304, orMaster controller 300 is controlled peripheral device 304 and is switched to mode of operation etc. Can be as for peripheral device 304One touch-control board device, a mobile device, or an electronic product that includes simple and easy personal calculator function.Certainly, peripheral device 304 also drives by a peripheral device chip, and detailed content is as follows.
Please also refer to Fig. 3 and Fig. 4, Fig. 4 is showing of the embodiment of the present invention one peripheral device chip 40Intention. As shown in Figure 4, peripheral device chip 40 is arranged in peripheral device 304, and peripheral deviceChip 40 include a frequency selector 400, a controller 402, a buffer selector 404 andOne peripheral device buffer 406. In addition, peripheral device chip 40 also couples a serial interfaces buffer 408.Specifically, peripheral device chip 40 passes through serial interfaces 302, reception one periphery frequency source MCLK,One serial interfaces frequency source SICLK, carry out a power save signal PD of autonomous controller 300, and come autonomousAt least one data DATA of controller 300 or arbitrary peripheral device 304. Frequency selector 400 first connectsReceive the power save signal that periphery frequency source MCLK, serial interfaces frequency source SICLK and master controller sendPD, judges that according to power save signal PD a frequency selection result is that periphery frequency source MCLK or sequence connectMouth frequency source SICLK, the mode of operation that further determines peripheral device 304 is a normal mode (i.e. fortuneOperation mode) or a battery saving mode. Controller 402 is electrically connected to frequency selector 400, in order to receiveFrequency selection result and data DATA, its middle controller 402 can further comprise a decoder and turnChange the kenel of data DATA, in order to provide peripheral device 304 to carry out the access exclusive disjunction of data DATAAction. Buffer selector 404 be electrically connected to controller 402, peripheral device buffer 406 andSerial interfaces buffer 408, receives power save signal PD and data DATA, and according to power save signal PDJudge whether to transmit data DATA to peripheral device buffer 406 or serial interfaces buffer 408.
Preferably, the periphery frequency source MCLK that peripheral device 304 uses is synchronized with master controller 300The master controller frequency source (not shown) using, in order to do data DATA is unlikely in transmitting procedureLose. Moreover peripheral device 304 is by controller 402 and serial interfaces 302, by data DATAReturn to master controller 300 to reach exchange and the backup of data DATA. In addition, in this embodiment,Data DATA in serial interfaces 302, be with the kenel transmission of a sequence data at master controller 300 and304 of peripheral devices. When data DATA enters after peripheral device 304, data DATA is by controlThe decoder of device 402 processed is converted to a parallel data, and (data DATA is stored in different buffersPeripheral device buffer 406 or serial interfaces buffer 408). If include multiple in electronic system 30Peripheral device 304, arbitrary peripheral device 304 is to correspond to a private code, and master controller 300By the specific peripheral device 304 of private code search, in order to specific periphery is filled according to different demandsPut 304 and assign control instruction, in order to do making different instruction all can send and take office via master controller 300 exactlyOne peripheral device 304. For instance, master controller 300 is except sending aforesaid power save signal PD,Also can send wake-up signal (not shown), in order to wake the peripheral device 304 that is in battery saving mode up,Further provide peripheral device 304 to switch its mode of operation. Certainly, master controller 300 also comprises transmissionOther control instruction, but its non-technical characteristics of the present invention is not repeated herein.
In simple terms, if user's wish is further controlled the work of peripheral device 304 by master controller 300Operation mode, peripheral device 304 is according to power save signal PD (or wake-up signal), further switches and works asBefore the operating frequency that used, and determine the mode of operation of peripheral device 304. For example, work as peripheral device304 while entering battery saving mode from mode of operation, and power save signal PD transfers high state to, and frequency selector400 also Selective sequence interface frequency source SICLK is as the operating frequency that drives peripheral device chip 40, rightShould sequentially the data DATA receiving be transferred to serial interfaces buffer by 404 of ground buffer selectors408; When peripheral device 304 enters normal mode from battery saving mode, power save signal PD transfers low state to,And frequency selector 400 also selects periphery frequency source MCLK as the work that drives peripheral device chip 40Working frequency, 404 of buffer selectors are sequentially transferred to periphery by the data DATA receiving accordinglyDevice buffer 406, its operational detail can further be understood by following different embodiment, but non-in order toLimit category of the present invention.
Please refer to Fig. 5, Fig. 5 is that one embodiment of the invention is worked as peripheral device 304 and entered province from mode of operationThe coherent signal schematic diagram of power mode, wherein aforesaid single power save signal PD can be by multiple numeral lettersNumber any combination, in order to reach identical effect, be only illustrative at this. As shown in Figure 5, main controlDevice 300 is the moments that transfer low state by a serial interfaces interrupt signal SI_Interrupt from high state to, instructionThe built-in counter MCU_Counter of peripheral device 304 (works from a working cycles Main_LoopCirculation is to provide peripheral device 304 and carries out general computing) enter a battery saving mode PD_Mode and maintain oneThe section time. At the same time, a memory data signal PD_Store of peripheral device 304 is driven to an arteries and veinsRush signal, in order to transmit data 1～n to serial interfaces buffer 408, and by one of peripheral device 304Serial interfaces buffer selects signal SI_Buffer to transfer high state to, and instruction master controller 300 is directly deposited since thenGet the data 1～n of serial interfaces buffer 408, peripheral device 304 also enters battery saving mode and pass simultaneouslyClosed cycle side frequency source MCLK. In the case, because peripheral device 304 does not use periphery frequency sourceMCLK and use serial interfaces frequency source SICLK instead, in order to the operating frequency as its internal circuit, noBut reach outside effect of power saving, data 1～n has also been sent to serial interfaces buffer 408, master controller300 by not being limited to the peripheral device 304 that enters battery saving mode, can capture at any time the data of having transmitted1～n, avoids reawaking the rear further work that just can carry out of peripheral device 304. Moreover, nowIf have the defeated arbitrary data of user's tendency to develop to peripheral device 304, also can not be limited to peripheral device 304Enter battery saving mode, cause master controller 300 and peripheral device 304 cannot link up generation Missing data.Therefore, the present invention not only reduces the stand-by period of system computing, the access of distribute data effectively,Transfer of data is effectively provided between master controller 300 and peripheral device 304.

Work as peripheryFrequency source MCLK has been stable periodicity square-wave signal, informs the counter that peripheral device 304 is built-inMCU_Counter prepares to enter battery saving mode and maintain a period of time from idle state (unknown signaling)T_PD, and preparation enters working cycles Main_Loop. Enter after working cycles Main_Loop sequenceData 1～n that interface buffer 408 and peripheral device buffer 406 all can receiving sequence interface transmit,Until a readout data signal PD_Load of peripheral device 304 is while being driven to a pulse signal, i.e. tableShow that peripheral device buffer 406 has completed reception data 1～n, now, the sequence of peripheral device 304 connectsMouth buffer selects signal SI_Buffer to be dragged down by correspondence, to inform 300 direct access weeks of master controllerData 1～the n of limit device buffer 406. Preferably, serial interfaces buffer 408 comprises a default skyBetween, reach stable and before T_PD after a while, pre-set space is enough at periphery frequency source MCLKDeposit the data 1～n having transmitted. Therefore, even if peripheral device 304 is still in battery saving mode or is just preparingEnter (being that periphery frequency source MCLK not yet reaches stable state) before normal mode, anyly transmitData 1～n also can not lose to some extent. Hence one can see that, and the present invention can solve the right of data access effectivelyResemble and use opportunity, significantly reduce system data and transmit contingent mistake and improve the efficiency of linking up,More effectively transfer of data is provided between master controller 300 and peripheral device 304.
Further, the working method of electronic system 30 and peripheral device chip 40 can be summarized as a sequenceInterface transmits flow process 70, as shown in Figure 7. Serial interfaces transmits flow process 70 and includes following steps:
